Large Neutrino-Dark Matter Interactions: EFT and UV Completions

Published:Dec 31, 2025 18:31
1 min read
ArXiv

Analysis

This paper explores the theoretical possibility of large interactions between neutrinos and dark matter, going beyond the Standard Model. It uses Effective Field Theory (EFT) to systematically analyze potential UV-complete models, aiming to find scenarios consistent with experimental constraints. The work is significant because it provides a framework for exploring new physics beyond the Standard Model and could potentially guide experimental searches for dark matter.

Orbital Magnetic Octupole and Anomalous Hall Effect in Solids

Published:Dec 30, 2025 14:46
1 min read
ArXiv

Analysis

This paper addresses a fundamental problem in condensed matter physics: understanding and quantifying orbital magnetic multipole moments, specifically the octupole, in crystalline solids. It provides a gauge-invariant expression, which is a crucial step for accurate modeling. The paper's significance lies in connecting this octupole to a novel Hall response driven by non-uniform electric fields, potentially offering a new way to characterize and understand unconventional magnetic materials like altermagnets. The work could lead to new experimental probes and theoretical frameworks for studying these complex materials.
Reference

“The paper formulates a gauge-invariant expression for the orbital magnetic octupole moment and links it to a higher-rank Hall response induced by spatially nonuniform electric fields.”

Gauge-Invariant Phase Mapping with Structured Light in Atomic Systems

Published:Dec 29, 2025 17:54
1 min read
ArXiv

Analysis

This paper proposes a method to map arbitrary phases onto intensity patterns of structured light using a closed-loop atomic system. The key innovation lies in the gauge-invariant loop phase, which manifests as bright-dark lobes in the Laguerre Gaussian probe beam. This approach allows for the measurement of Berry phase, a geometric phase, through fringe shifts. The potential for experimental realization using cold atoms or solid-state platforms makes this research significant for quantum optics and the study of geometric phases.
Reference

“The output intensity in such systems include Beer-Lambert absorption, a scattering term and loop phase dependent interference term with optical depth controlling visibility.”
